Dear Dave and Greg,
Thank you for your mails, Dave, and the quality of your code, which has
made it possible for me to follow it and modify it.
I can recommend and sign-off on your EHCI_HCD buggy devices maxPacketSize
patch, because it made the devices work under usbnet at the EHCI_HCD end.
I am now able to ping in both directions over the F5U258 cables (and over a
pair of F5U258 cables concurrently) from a USB 2.0 EHCI_HCD on 2.6.23.14
kernel with your EHCI_HCD patch for buggy devices to a machine running
2.6.17.14 with USB1.1 on a UHCI_HCD controller laptop.
- No changes were required on the machine where the UHCI_HCD device
is, so I only needed to do a compliation of the kernel for the EHCI_HCD
patch.
So it is working and does not drop any datagrams at all.
There is a message showing in dmesg about ifconfig having problems with
endpoint 0. Endpoint 0 shows up under some USB test software as the
configuration descriptor and the test software shows 4 endpoints, but lsusb
-v only shows 3.
I will try and brew a patch file as mentioned earlier, Greg.
But all I have really done is modify the plusb.c file to have the VID and
PID values of the device in it and then test it in conjunction with your
very helpful help. Since Belkin are a popular manufacturer, then I guess it
would be good to have these values in the software?
- I will try and supply a diff for the usb devices list as well.
More details below. Please let me know what you think.
Kind Regards,
Tony

I'm not sure such a patch is possible. There are hardware limitations
to cope with ... and I can't possibly see all the full speed host
controllers supporting such a workaround.
Your particular device looks deeply broken ... as if maybe an internal
EEPROM with descriptor data spped high and full speed sections.
